    • A television-camera is used to obtain a video image of an area to be monitored, the video image being displayed on the display screen of a television receiver. A light pin is used to set plural display points on the display screen so as to define a specific area within the video image. By comparing density levels of successive frames of the video image, a moving object is detected. An alarm is generated if a detected moving object contacts a set number of the display points set using the light pin. Also, by employing two or more television-cameras oriented at different angles with respect to the area to be monitored, and by setting respective sets of display points for each the thus obtained video images, reliability of the alarm detection can be enhanced.
    • 使用电视摄像机来获取要监视的区域的视频图像,该视频图像被显示在电视接收机的显示屏幕上。 光引脚用于在显示屏幕上设置多个显示点,以便定义视频图像内的特定区域。 通过比较视频图像的连续帧的浓度水平,检测移动物体。 如果检测到的移动物体接触使用光引脚设定的设定数量的显示点,则产生报警。 此外,通过采用相对于要监视的区域以不同角度定向的两个或更多个电视摄像机,并且通过为由此获得的每个视频图像设置各组显示点,可以提高警报检测的可靠性。
